5.6.3.5 Set Signal Path (M)
This is the command for switching the switch module
ooo
to the input port
iii
.
<STX>Mooo:iii<checksum><ETX>
e.g.
<STX>M:001:002AA<ETX>
with:
ooo
= the switch module number in the range
001…016
;
iii
= the input port number to which the switch module is to be connected to,
either
001
or
002
.
The device confirms the command with an
<ACK>
if the command is accepted and
with a
<NAK>
otherwise.
Note:

It is possible to issue a switch command for an empty slot or for a slot
populated with a passive module or with a distribution amplifier module.
Naturally, there is no execution of the switch command.

If a parameter exceeds the permissible range or if the device is not in Remote
Mode, a
<NAK>
is returned!
5.6.3.6 Select Remote Control Mode (PMCI/PMCE)
Via these device specific commands, the operation mode can be either set to
Auto Mode (
PMCI
) or to Remote Mode (
PMCE
); please refer to chapter 5.1.
<STX>PMCI<checksum><ETX>
i.e.
<STX>PMCI29<ETX>
and
<STX>PMCE<checksum><ETX>
i.e.
<STX>PMCE25<ETX>
The device confirms both commands with an
<ACK>
if the command is accepted and
with a
<NAK>
if the device is in Local Mode.
Note:

If the Auto Mode is activated via the
PMCI
command, this implies the usage of
the device defined by the Auto Mode Assignment of the Web Interface
(chapter 5.5.7.3.2).

If Auto Mode is activated, no switching command (
M
, chapter 5.6.3.5) is
executed. The
PMCE
command has to be issued first, to get back the remote
switching control via Sandar Prosan protocol.
5.6.3.7 Select Echo in Local Mode (PME0/PME1)
Using these device specific commands "Echo in Local" can be
disabled (
PME0
) or enabled (
PME1
).
If "Echo in Local" is disabled and if the device is in Local Mode, the device responds
to queries (
Q
,
XR
,
AM
or
AMA
,
S
or
SA
) with an
<ACK>
character only.
<STX>PME0<checksum><ETX>
i.e.
<STX>PME012<ETX>
and
<STX>PME1<checksum><ETX>
i.e.
<STX>PME113<ETX>
The device confirms both commands with an
<ACK>
if the command is accepted and
with a
<NAK>
if the device is in Local Mode.
Note:

Alternatively, "Echo in Local" can be enabled or disabled within the CPH setup
of the Web Interface (please refer to chapter 5.5.7.2.3).
